Well, there's the obvious: if you're going to be cloning or creating enough systems to invest the time up-front to develop easy procedures...why aren't you running VM? There's no method so easy that it will save you the time of creating three or four images, I'd say. If you're talking about a dozen, there are lots of useful tricks: put /usr in a shared read-only DCSS, IPL from NSS, use the PARM LINE patch to customize per-image booting without having to rewrite the IPL record, put multiple layers of swap at different priority on V-DISK, read your guest's configuration files at boot time from an external repository.... All of these, however, require z/VM. If you're running in LPAR, then, other than getting a clean base copy and DDRing *it* rather than a running system, I can't think of anything. > Since we use CDL format DASD which creates a VTOC with files such as > LINUX.VLNX001.PART0000.NATIVE, could I mount this under z/OS Unix System > Services and access it? Not yet (that I'm aware of). There is work on a CMS driver for the ext2 filesystem, and the hope is that it won't be too hard to port to z/OS. However, it's not ready yet, and it wouldn't help with Reiserfs anyway (although it would read ext3 just fine, of course).
